Final details are coming in for Kilian Jornet’s Tahoe Rim Trail. Salomon has now revealed that Kilian will begin his attempt at 5 a.m. on Monday, September 28 from Tahoe City, California. As such, everyone in the Americas will have something to follow throughout their workdays Monday and Tuesday. We’ll be updating you on Kilian’s progress as often as we can on Twitter. [Follow @iRunFar on Twitter] We’re not greedy – we’ll certainly point out others who’ll be providing updates from the trail. [We suspect @Salomon_Running will.] Keep reading to find out more details about next week’s Tahoe Rim Trail run, including a weather update, Kilian’s projected splits, his pacers and support, and some commentary. [They’re for well under record pace.] Up until the run starts, we’ll provide any changes to paces, coverage, and other details regarding the run in updates to this post.

WeatherFirst off, the weather forecast appears to be sticking in Kilian’s favor. Unlike the sweltering heat of his record breaking run of Corsica’s GR20 trail this summer, temperatures will range from warm to cold. The forecast for the start/finish in Tahoe City is for a high of 63F (17C) on Monday, a low of 37F (3C) Monday night, and a high of 49F (9C) on Tuesday. If Kilian’s run extends into Tuesday night, he’ll face a chilly low of 28F (-2C). Kilian will generally face temperatures that are cooler than those forecast. The forecast is for one of the lowest points on the route, Tahoe City, which sits at approximately 6,500′ (~2,000m). The trail spends much time around 8,000′ (2,500m), which should be a few degrees (5F/3C) cooler, while the high point at 10,319′ (3,145m) could be 10-15F (5-8C) cooler.

There should be partly to mostly cloudy skies throughout the run. There’s little chance of rain or snow with only light precipitation possible if it comes. The biggest weather news could be the wind. The National Weather Service forecast for the area notes the passage of a strong weather front on Monday:

SOME COOLING IS EXPECTED MONDAY BEFORE A STRONG COLD FRONT WILL MOVE THROUGH THE REGION TUESDAY. AHEAD OF THIS COLD FRONT… STRONG GUSTY WINDS ARE POSSIBLE MONDAY NIGHT AND TUESDAY. THE STRONGEST WINDS WILL OCCUR OVER THE RIDGES AND WIND PRONE AREAS. BEHIND THE FRONT…

We hope Kilian brought one of Salomon’s Windstopper jackets for the ridges!

Kilian’s Projected SplitsOk, now on to the juicy stuff… the splits for the full 165 miles (265k). Keep in mind that Tim Twietmeyer holds the record in 45 hours and 58 minutes. First, Kilian’s most predictable segment, the first 60 miles, which he’ll run during daylight (once the sun comes up) on Monday.

CommentaryHere’s what we think. We think Kilian has the tools, trail conditions, and support to finish in the last rays of daylight on Tuesday. He can take 8 hours of this record and finish in under 38 hours. So where’s he going to make that up over his projections? At the end. This Catalan gives himself 15 hours to cover the final 47 miles (76 kms). It’d be hard for Jornet to say he’s going to run much faster than 40 hours, but his plan for the opening 100 miles (99 miles in 21 hours) is conservative enough for this trail that we think he can keep rolling for awhile after that, especially once the sun comes up on Day 2. We think Kilian can make up the most time in the section from Echo Lake (mile 118/190 kms) to Dicks Pass (mile 129/208 kms). Unless KJ plans on taking a nap, we can’t imagine any 11 miles (17.7 kms) of trail taking him 5 hours.

Pacers/SupportSo far the pacers we know of are Salomon runners Adam Chase and Ross McMahan; Kevin Johnson from Salomon’s North American headquarters; and me, iRunFar’s very own Bryon Powell. We know of two other probable pacers, but will wait to announce them until we have confirmation. [Update 9/26 1 pm PDT] Josh Korn, a “friend of Salomon” will also be pacing Catalan KJ on the TRT.

Kilian will be well supported by Salom
on folk from the US and Europe. They’ll provide him with food and drink at 17 spots along the course and provide you with great images and commentary afterward.
